#### Filter Type: Median

This type is only available for Perceptron sensors.

Median filter type

The Median filter smooths laser stripe data by computing a new location for each pixel. For each pixel in the stripe, the median filter takes the nearest neighboring pixels, computes the median, and uses the median for the new location of the pixel.

Neighbor #: This value determines the number of total neighboring pixels that the software considers when PC-DMIS calculates a new location of any given pixel in a single stripe.

For example, if the number of neighbors is 9, then for each pixel in the stripe, the filter takes four data points to the left and four data points to the right (for a total of 9 pixels, including the current one). It then computes the median and uses it for the location of the current pixel.

Point Reduction Filter: This check box determines whether PC-DMIS filters points along the scan line. If the check box is marked, you can select the desired percentage of total points to filter. If the check box is cleared, the complete data set is acquired without any filtering.
